Pin



G. S. LIGHT PIN April 13, 1937.

Filed Dec. 11, 1935 OANEY Patented Apr. 13, 1937 UNITED STATES PATENT OFFICE Claims.

O in the construction and use of which the object herein set out, as well as others, may be attained is illustrated in the accompanying drawing in p which Figure 1 is a side view of a pin embodying my invention.

Figure 2 is an end view of the same.

Figure 3 is a view in lengthwise section through the head and a portion of the shank of the pin.

Figure 4 is a detail view illustrating a little different form of the under surface of the head.

Figure 5 is an isometric perspective view illustrating the manner of using the pin.

In the use of common pins as heretofore made the heads have been comparatively small with a result that a continued application of the fingers to the heads of such pins in pinning clothing, as in the manufacture of shirts, results in injury to the fingers. Further than this the small heads of such pins when applied toclothing become 30 practically buried in the cloth so that it is a difficult matter to tell which is the head and which is the point of the pin with the result that the fingers are liable to be pricked, thereby causing injury.

, In the manufacture of pins with fiat heads as heretofore practiced it has been impossible to increase the sizes of the heads and therefore since the time the art was established small headed pins have been in vogue largely from a matter of necessity. This results from the fact that with the use of wire of a certain size suitable for pins it has been impossible to produce a larger head.

By the practice of my invention I am enabled to produce from wire of the same size as hereto- 45 fore employed a much larger head on a pin than has heretofore been possible, thereby providing a large surface for contact of the fingers, thereby avoiding the result hereinbefore set out, and the size of the head is such that it can be readily dis- 50 cerned and will not become buried in the cloth,

60 the head is also of conical shape, or it may be slightly curved radially as may be desired. The under and outer surfaces are joined by a band I I which may be of cylindrical shape or which may be slightly rounded, as may be desired.

It will be understood that the heads of the pins, as is common in pins of this type, Will be of polished or otherwise shining material, and the conical shape of the head therefore gives off much brilliancy so that the head is readily discernible and this is a further aid in enabling the head to be seen when the pin is inserted in fabric.

The conical shape of the head, as hereinbefore mentioned, enables a much larger head to be produced on a pin formed from wire of a certain size than has heretofore been possible, this conical shape permitting fiow of metal in such a way as to produce such enlarged head. In fact I am enabled to produce a head having a diameter at least three or four times as great as that of the wire and a thickness of head which is equal at least to the diameter of the wire shank itself.

While in the preferred form of pin the under side of the head is of conical or outwardly curved shape, I contemplate that various other forms may be given to the under surface, as for instance, a substantially fiat under surface I 2, as shown in Fig. 4 of the drawing.

I claim:

1. A wire pin composed of a single piece of unannealed hard drawn wire including a pointed shank and a head having an outer end conically shaped outwardly and a conically shaped under surface.

2. A wire pin composed of a single piece of unannealed hard drawn wire including a pointed shank and a head having an outer end conically shaped outwardly with a rounded apex and a thickened under surface.

3. A pin composed of a single piece of unannealed hard drawn wire including a pointed shank and a head having an outer surface conically shaped outwardly and a thickened under surface with a cylindrical part joining the two surfaces at a median plane extending crosswise of the head.

4. A wire pin composed of a single piece of unannealed hard drawn wire including a pointed shank and a swaged head having an outer surface conically shaped outwardly with a rounded apex and an under surface with a thickened edge joining said conical and under surfaces.

5. A wire pin composed of a single piece of unannealed hard drawn wire including a pointed shank, and a swaged head decreasing in diameter outwardly with the greatest diameter of the head at least three times the diameter of the wire comprising the shank of the pin, and said head having a depth at least as great as the diameter of the wire.
